PORTABLE LAME.

Application filed October zofieai. Serial No. 508,977.

To all whom it may concern:

Be it known that we, J OHN A. AMos and ERNEST WANAMAKER, citizens of theUnited States of America, residing at 'the city of St. Louis, State ofMissouri, and at Chicago, county of Cook State of Illinois,respectively, United States of America, have invented a certain new anduseful Portable Lamp, of which the following is such a full, clear, andexact description as will enable any one skilled in the art to which itapp'ertains to make and use the same, reference being had to theaccompanying drawings, forming part of this specification. I

Our invention relates to a portable electric lamp comprising a lampguard, handle, and

socket constructed and assembled in a novel manner v Among the objects.of the invention are to producea portable lamp which is of simple butrigid mechanical construction and may be readily disassembled for theinsertion of an electric light bulb; which will be completely free fromany exposed conducting parts and possibility of accidental grounds;and'one in which the socket, handle and guard are rigidly connectedwithout the use of any screws engaging with wood, or' otherv relativelysoft material. Other objects and advantages of our improved portablelamp will appear from the following-more detailed description. f

In the accompanying drawings, Figure l is a side elevational viewof'alam embodying our invention;'Figure 2 is a longitudi nal crosssectional view; and Figure 3 is a' transverse cross sectional view onthe line 3-3 of Figure 2. V

1 represents a handle which is preferably of wood or other suitableinsulating material. The guard for .the electric lamp 5 is sectional andin the preferred form comprises two separable parts 2 and 3 and thelower port-ions of the guard members are provided with inwardlyprojecting flanges 7 adapted to be seated in a circumferential groove' 8in the lamp receptacle 4. The lower ends of the guard portions are alsoprovided with inwardly projecting flanges 9 to engage with acircumferential groove in the handle 1. The hook 6 is attached to theouter end of the guard member 2 and guard member 3 is provided with aprojectlng boss having an. opening therethrough for the passage of thehook. Both portions as ofthe guard members are provided with a pan ofears l0 and the screws ll cooperating vwith these ears serve to clampthe guard members in position to embrace and hold the handle and thelamp socket.

The conducting wires for the lamp extend through the handle and strainon the connections of the conductors with the lamp socket is preventedby the strain relief member 12 which clamps over the conductors andbears against the lower wall of the recess in the handle into which thesocket extends.-

.The lamp, handle and socket are assembled by first threading hook 6through the boss on the outer end of the guard member 3 and thenbringing the inner ends of the ,guards together over the lamp socket andhandle. e

It will be noted that in the construction described, thelamp socket iscarried bythe lamp guard and in rigid relation thereto and connectionbetween the handle and guard members is made without the use of screwsor threads. The outer wall of the socket is of insulating material,and'no conducting parts are near or adjacent to the lamp guard or handleand the apparatus is thus rendered entirely safe for handling. Thesocket being carried by the guard and 5 rigidly held thereby cannotbecome loosened and the lamp is thus securely held from accidentalbreakage by being brought into contact with the .walls of the guard.

. In the. form shown guard member 2 is'iinerforateand serves as areflector but if Fight in all directions is desired it can be made inskeleton form like guard member 3. Having fully described our invention,

What we claim as new and desire to secure by Letters Patentof the UnitedStates is: 1. In a portable lamp, the combination of a handle providedwith a circumferential groove, a lamp receptacle provided with :1

circumferential groove,'and a sectional lamp guard each section beingprovided with two inwardly projecting shoulders adapted to register withthe grooves in the lamp receptacle and the handle.

2. In a portable lamp, the combination of a handle, a lamp receptacle,and a metal damp guard comprismg separablesections, said handle and.receptacle being each clamped between the sections of the guard V andthe portions of the receptacle and han' dle engaged by the guard beingof insulating material.

3. In a portable lamp, the combination the guard by being clampedbetween the parts thereof.

6. Ina portable lamp, the combination of a handle provided with a.circumferential groove, a lamp receptacle provided with acircumferential groove, asectional lamp guard each'sectlon belngprovided with two inwardly projecting shoulders adapted to register withthe grooves in the lamp receptacle and the handle, and means for holdingsaidshoulders in engagement With the grooves whereby the receptacle andhandle are held in fixed relation.

In testimony- Whereof, We have hereunto set our hands'and affixed ourseals.
